Antisocial behavior and psychopathic traits are subject to complex patterns of inheritance, gene--environment interactive effects, and powerful environmental influences. Yet genetic factors are important in the etiology of antisocial behavior and psychopathic traits, and identifying youth with an elevated genetic risk may lead to improved interventions and preventive efforts. Additionally, research revealing the importance of gene--environment interactions in the development of antisocial behavior and psychopathic traits should be harnessed to promote more rehabilitative, developmentally appropriate policies to benefit youth in the juvenile justice and social welfare systems.
Keywords: antisocial personality disorder; callous-unemotional traits; conduct disorder; gene-environment interactions; psychopathy.
